' Our invention relatesto combing machines for combing cotton or other fibrous mate rials and has'refer'ence to improved means for clearing the detaching rollers from fibers so that same are kept clean automatically by the improved mechanism to be set'forth.

It is known to use a hingedboard with flannel covered face to'bear on the detaching rollers such board being turned-up for cleaning from time to time, and it is also known to use a rotatable flannel cover-ed clearer roll, but these devices are not very effective with result that slubs or matted fiber is apt to fall down and become incorporated in;

the combed material, producing faults and interfering with thequality of the ultimate varn. v

V As thecombing machine is the last cleaning apparatus in the range of preparation machinery for cotton it is important the combed material pass forward free from all slubs or objectionable accumulations o ffiat waste, as such cannot afterwards be 'QllIlllnatedl Such results are not howeverobtamable: with known clearing means. e use a flannel covered ,revolving clearer roll which is driven frictionallyand. accord ing to "our inventionweperiodically and automatically clear the same by using a revolving stripping and storage fillet covered roller which is positively and automatically driven so as to effectively strip the revolving clearer so that a clean surface isalwayscoming into action and the stripped material is stored'until an opportune time for its removal.

The accompanying drawing illustrates our improvements and is referred to in the following detailed description. Only so much of-the comber mechanism is illustrated as ill enable our idea to be properly under stood.

In such drawing Fig. 1 is a side elevation from the lef hand end of the comber head the view showing the revolving stripping andstorage fillet covered roller and its actuatmg gear.

Fig. 2 shows a front view of the mecha being held by studsapplied at 7' j covered rollw which constitutes the 'revolv-. ing'clearer. This roll (bis-preferably madefrom steel tubing and is trul .cylindrical; Ithas trunnion ends a, a and isloc'a'ted between the front and back leather covered. detaching rollers and is driven by. friction from the back detaching roller Z), which is shown, and this in the known way. .The trunnions of the clearer roll a. are carried in bearings in small brackets such as those marked 0, a from the cranked. arms d, d which embrace "the known fulcrum or rocking shaft 6. The slots c and studs c provide for adjustment of the brackets c, a and consequently of the revolving clearer a. As; it is very important such revolving clearer a should not slip or fall back, as this is apt to cause any; fiber collected'thereon to become detached and fall into the combed ma-- terial, we use a geared ratchet .mech'anism whereby any fractional advance of the re volving clearer aonce made is assured. As an example, we show a small pinion f on the end of the axleatrwhich gearsintoia larger pinion g on a stud axle 9, this largerpinion 9' having combined with it a finely Cutd'atCh-f et wheel h; with which aipawl-h5 pivoted at if engages. The pivot h? of thepawly/L' is fixed iii-the 'bracketc. The stop marked ifiis to preventthe pawl h jumping too high and failing'to come i nto gear. The combination represents a suitablecgeared ratchet group but any other delicate non-returnmechanism' may be used whicliso actsthat anyrfractional rotation of the revolving 'clearera once made is assured. The letter w denotes the known weight hooks.

In connectlon wlth and mounted above the fianne l covered revolving clearer roll a which contacts with and is driven by the back detaching roller 6 we mount a revolving stripping and storage fillet covered roller i. This has an aXle z" the extremities of which fit into slots in the brackets j, j which are bolted to the inside faces of the cranked arms (Z, (Z. These brackets are adjustable brackets are slotted at y and the screws permit of ready setting. The revolving stripping and storage fillet covered roller 2' acts as "a stripper or cleaning roller to the flannel covered revolving clearer a, and as a storage cylinder for the material removed, the fiber taken'from the fia'nnel'covered re m The.

volving clearer roll being embedded in the dents on the roller 2' and thereby retained untilth-e attendant strips the said roller We arrange to slowly drive the revolving stripping and storage fillet covered roller 2' in any convenient way. For example; we may fix a ratchet wheel 70 on the axle-z and actuate this from a slotted lever Zloose onthe axle 2" said lever Z having a pawl Z pivoted at Z withcheck stop Z Such slotted lever Z could be worked by a pin or stud m adjustably 'mounted on a bracket 1% secured tothe pedestal of the front detaching rollers or otherwise.

--The actuation of the flannel covered revolving" clearer. roll a and the revolving strippingand storage fillet covered roller shown) as those conversant with theactionof the Nasinith or like comber will understand, and, if the mechanism be watched at work, it will be seen thedetacl'iing rollers are kept quite-clear of fibers and that the revolving stripping and'storage fillet cov ered roller keeps the flannel covered revolving clearer roll clean all the time, and slubs and flat waste cannot become detached. The result is, a great decrease in faults in the combed material and by reason of the need "forless attention an increase in pro ductioni takes place. 1 The revolving stripping'and storage fillet covered roller is easily'cleaned or strippe'dfrom tim'eto time by a wire brush, because just as the waste easily embeds and becomes compacted in the overhanging teeth'so-the waste fibers are easily plucked out by a wire brush operated to lift the fiber out. It is seen that the revolving stripping and storage fillet covered roller 5 can be easily detached for cleaning,

&c. by release of the pin m which leaves the roller at liberty to be lifted out of itsslotted bearings, Accessis also easily had for the varnishing of the leather covered detaching ll wm I. .f. .1 1 i Wemay weight the front detaching roller by"'l1ooks'witl1 suspende'dbar engagingth'e two hooks and by a weight hung on the sus-I pended bar.

The dents on the roller 2' may be variously arranged and it may be found that a revolving brush'would serve "as the cleaning and storage element suchbeing obviously only an equivalent to what we havedescri'bed and ers of combing machines the combination of a driven revolvable stripping roller having a brush-like covering, a revolving clearer roll, and automatic driving means for ensuring fractional'rotation in one direction of. the revolvalole stripping rolleri 3;Inco1nb1ng machlnes and in connection with the detaching rollers thereof, a revolv ing stripping roller, a fillet clothing-there-. on, a revolvlng clearer roll to which the 're-i volving str pping roller works, "and geared means for ensuring fractional rotation'in one direction only of tlie revolving stripping roller. In testimony whereof we have signed our names to this specification.
